	History:

	Modified by cmetz for OPIE 2.4. Added sequence number limits. Added
		struct opie_otpkey and made many functions use it. Added
		opiestrncpy(). Include header with libmissing prototypes.
	Modified by cmetz for OPIE 2.32. Added symbolic flag names for
		opiepasswd(). Added __opieparsechallenge() prototype.
	Modified by cmetz for OPIE 2.31. Removed active attack protection.
	Modified by cmetz for OPIE 2.3. Renamed PTR to VOIDPTR. Added
		re-init key and extension file fields to struct opie. Added
		opie_ prefix on struct opie members. Added opie_flags field
		and definitions. Added more prototypes. Changed opiehash()
		prototype.
	Modified by cmetz for OPIE 2.22. Define __P correctly if this file
		is included in a third-party program.
	Modified by cmetz for OPIE 2.2. Re-did prototypes. Added FUNCTION
                definition et al. Multiple-include protection. Added struct
		utsname fake. Got rid of gethostname() cruft. Moved UINT4
                here. Provide for *seek whence values. Move MDx context here
                and unify. Re-did prototypes.
	Modified at NRL for OPIE 2.0.
	Written at Bellcore for the S/Key Version 1 software distribution
		(skey.h).

 *
 * dli_htype is a "hook type" - 0 for incoming packets, 1 for outgoing
 * packets, and 2 for packets arriving from another zone on the same
 * machine.
 *
 * dli_pktlen is the length of the packet data following the pseudo-header
 * (so the captured length minus dli_pktlen is the length of the
 * pseudo-header, assuming the entire pseudo-header was captured).
 *
 * dli_ifindex is the interface index of the interface on which the
 * packet arrived.
 *
 * dli_grifindex is the group interface index number (for IPMP interfaces).
 *
 * dli_zsrc is the zone identifier for the source of the packet.
 *
 * dli_zdst is the zone identifier for the destination of the packet.
 *
 * A zone number of 0 is the global zone; a zone number of 0xffffffff
 * means that the packet arrived from another host on the network, not
 * from another zone on the same machine.
 *
